Luggage case

ABSTRACT

A luggage case includes a main body, a pair of first protective units disposed on two upper corners of a rear face of the main body and a pair of second protective units disposed on two lower corners of the rear face of the main body. Each first protective unit includes three connected plates and has a first chamfer face corresponding to an upper edge and one of two side edges of the rear face of the body. Each second protective unit includes three connected plates and has a second chamfer face corresponding to a lower edge and one of the two side edges of the rear face of the body. The upper edge, the lower edge and the two side edges of the rear face of the main body has a first curved face corresponding to the first chamfer face and the second chamfer face. The luggage case of the present invention can prevent hit and wear and be assembled simply.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to a luggage case, and more particularlyto a luggage case having protective units disposed on corners of theluggage case to prevent the luggage case from hit and wear.

(b) Description of the Prior Art

There are various luggage cases on the market. For example, a softluggage case is made of textile fabric, which comprises a soft mainbody, a soft cover and a zipper to lock the main body and the cover. Ahard luggage case is made of a plastic material by injection molding.The conventional luggage case has a hollow rectangular body with a rightangle at each corner of the body. The corners of the luggage case areeasy to hit or rub against other articles when the user draws or pullsthe luggage case, which not only influences the pulling of the luggagecase but also damages the appearance of the luggage case. Therefore, itis necessary to provide a protective structure to protect the edges andthe corners of the luggage case.

In addition, the conventional luggage case comprises two wheels coupledto the bottom of the luggage case and foot pads to support the luggagecase, so the luggage case can be pulled and placed steadily. However,the wheels, the foot pads and other parts are not an integral whole. Forinstance, they are not integrally formed with an anti-wear structure orthe base of a pull rod, so the assembly of the luggage case iscomplicated due to many parts. This is not cost-effective.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a luggagecase, which comprises first protective units and second protective unitsdisposed on corners of a luggage case. The first and second protectiveunits and a main body of the luggage case have chamber faces, preventinghit and wear.

A secondary objective of the present invention is to provide a luggagecase, which has slots formed on the first and second protective unitsfor insertion of a strap, so the first and second protective units canbe used to connect the strap and the main body.

Another objective of the present invention is to provide a luggage case,which provides wheels coupled with the second protective units, so theluggage case can be assembled simply.

A further objective of the present invention is to provide a luggagecase, which provides third protective units with support blocks to holdagainst the ground.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way ofexample only, with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 5, a luggage case according to a preferredembodiment of the present invention comprises a main body 1, a pair offirst protective units 2 disposed on two upper corners of a rear face 11of the main body 1, and a pair of second protective units 3 disposed ontwo lower corners of the rear face 11 of the main body 1.

As shown in FIG. 6 and FIG. 7, each first protective unit 2 comprisesthree connected plates 21 to wrap portions of the rear face 11, an upperface 12 and one of two side faces 13 of the main body 1. The threeplates 21 are integrally formed with a plastic material to constitutethe first protective unit 2. The first protective unit 2 further has afirst chamfer face 22 corresponding to an upper edge and one of two sideedges of the rear face 11 of the body 1. The first chamfer face 22 hasan angle of 30 degrees to 45 degrees.

As shown in FIG. 8 and FIG. 11, each second protective unit 3 comprisesthree connected plates 31 to wrap portions of the rear face 11, a lowerface 14 and one of the two side faces 13 of the main body 1. The threeplates 31 are integrally formed with a plastic material to constitutethe second protective unit 3. The second protective unit 3 further has asecond chamfer face 32 corresponding to a lower edge and one of the twoside edges of the rear face 11 of the body 1. The second chamfer face 32has an angle of 30 degrees to 45 degrees.

As shown in FIG. 1 and FIG. 5, the upper edge, the lower edge and thetwo side edges of the rear face 11 of the main body 1 have a firstcurved face 15 corresponding to the first chamfer face 22 and the secondchamfer face 32. The first curved face 15 has a preferred angle of 30degrees to 45 degrees, so that all the edges of the rear face 11 of theluggage case are smooth.

When the luggage case of the present invention is placed with otherarticles together, the first protective units 2 and the secondprotective units 3 can prevent the corners of the main body 1 from beingscrapped or damaged. Besides, when drawing and pulling the luggage case,the first chamfer face 22 of the first protective unit 2, the secondchamfer face 32 of the second protective unit 3 and the first curvedface 15 can avoid the luggage case from hitting other articles, so theluggage case can be pulled smoothly.

As shown in FIG. 1, FIG. 2, FIG. 7 and FIG. 8, the first protective unit2 has a slot 23, and the second protective unit 3 has a slot 33. Theslots 23, 33 are disposed on the plates 21, 31 relative to the side face13 of the main body 1. The slots 23, 33 can be inserted with a strap 4.Thus, the first protective unit 2 and the second protective unit 3 canbe used to connect the strap 4 and the main body 1. As shown in FIG. 1,FIG. 2 and FIG. 8, the second protective unit 3 of the present inventionfurther has a recess 34 at an outer side thereof for connecting with arotary wheel 35, such that the second protective unit 3 and the wheel 35are connected together, preventing the parts from scattering. Theluggage case of the present invention can be assembled simply.

As shown in FIG. 1 and FIG. 2, the main body 1 of the present inventionis a hollow rectangular case made of textile fabric, so that the softmain body 1 can be compressed. Alternatively, the main body 1 is ahollow rectangular case composed of hard plastic cases.

As shown in FIG. 12 and FIG. 13, the luggage case of the preferredembodiment of the present invention further comprises a pair of secondprotective units 5 on two lower corners of a front face 16 of the mainbody 1. Each third protective unit 5 comprises three connected plates 51to wrap portions of the front face 16, the lower face 14 and one of thetwo side faces 13 of the main body 1. The three plates 51 are integrallyformed with a plastic material to constitute the third protective unit5. The third protective unit 5 further has a third chamfer face 52corresponding to one of two side edges of the front face 16 and one oftwo side edges of the lower face 14 of the body 1. The third chamferface 52 has an angle of 30 degrees to 45 degrees. The two side edges ofthe front face 16 and the two side edges of the lower face 14 of themain body 1 have a second curved face 17 corresponding to the thirdchamfer face 52. The second curved face 17 has a preferred angle of 30degrees to 45 degrees, preventing hit and wear.

As shown in FIG. 12 and FIG. 13, the third protective unit 5 comprises asupport block 53 to hold against the ground. The support block 53 isintegrally connected with the third protective unit 5 to prevent theparts from scatting. The luggage case of the present invention can beassembled simply.
